accident priyanka's plan or not?

There are many spoilers/articles out there now about this accident sequence, some say it is Priyanka's plot against ArHaan, some articles its just an accident, nothing more.

What do you guys think ??

I personally think it's not her plan. Even after yesterday's episode when we saw how much vengeance she has against Aarushi, i still think priyanka is not capable of this.

She might not have ArHaan's best interests at heart at the moment. But priyanka so far is not this type of character at all.

Hoping CVS don't butcher her :/
